Handling rolled material

J GASSEN v HANDLING ROLLED MATERIAL Filed Aug. 21, 1935INVENTOR fast-,4 6/1555 7 ATTORNEY Patented Nov. 23, 1937 i'rso STATESPATENT or ies HANDLING ROLLED MATERIAL Application August 21, 1935,Serial No. 37,123 In Germany June 14, 1934 3 Claims (Cl. 198219) Myinvention relates to the handling of rolled material and particularly tothe conveying of rolled rods of steel to their bundling places orstations from the cold shears which cut the rods into commerciallengths.

This bundling is usually carried out by manual labour in that a certainnumber of rods is segregated, by means of hooks or like implements outfrom the bulk of rods on the delivery conveyer of the cold shearsand'then is tied fast into bundles or packs. The cold shears aregenerally operated so that they cut simultaneously very large numbers ofrods in rapid succession which requires a correspondingly large numberof ls 'bundles to be made up quickly to keep up with the output of suchmills. The. rods when delivered from the cold shears to the bundlingplaces are piled up in heaps so that the rods become very much entangledor matted with another. In the operation of unravelling the rods andcounting an exact number of them into the hooks it frequently occursthat the finished bundles either to deal with theoutput of the mill tobe ar-' ranged.

It is an object of my invention to facilitate the handling of largeroutputs of rod mills at the bundling places than is now possible and atthe same time to insure that each bundle is made up of the correctnumber of rods.

It is a further object of my invention to provide an improved apparatuswhich permits of arranging a sufiicient number of bundling places todeal with the output of modern rod mills.

It is a further object of my invention to prov vide for bundles ofdifferent sizes to be handled at one time. I

An apparatus embodying my invention comprises a shaking device by meansof which the 5 rods coming from the cold shears are spread out spacedapart in a single layer prior to their bundling. Thus, each individualrod is freed from entanglement with the adjacent rods and can be readilygrasped by hooks.

In the accompanying drawing, in which I have shown one embodiment of myinvention by way of example,

Fig. 1 is a part of the layout of a steel mill 55 plant, incorporatingmy invention;

the roller table IE to limit the distance by which 10 the individualgroups of rods are fed forward after each cutting operation. All theseparts are of well known design and therefore need not to be furtherdescribed.

Beside the roller table :2 is provided a shaking 15 device whichcomprises two groups of parallel bars l3 and I3 which with their endsadjacent the roller table l2 are supported upon eccentrics l4 and Mrespectively (Fig. 2) mounted on a common shaft I5, the said bars l3, I3having 20 straps or their equivalents cooperating with said eccentricsI4, Mflas shown in Fig. 2, so that rotation of said eccentrics resultsin said bars being oscillated vertically and, at the same time,reciprocated. The other ends of the bars are freely supported on rollersl6 mounted on a frame [1. As will be readily apparent from Fig. 2, theeccentrics l0 and M which act upon the two groups of bars l3 and I3 areoffset with respect to each other so that one group of bars is always inits raised position while the other group is lowered. For transferringthe rods from the roller table l2 to the shaking device, rocking membersl8 are swingingly mounted on a shaft l9, by means of which members therods are pushed 01f from the roller table to an inclined surface 20 atthe lower end of which vertically movable stops 2! are provided.

At the forward ends of the bars I3 and I3, the first bundling places arelocated which are gen- 40 erally designated in Fig. 1 by the referenceletter A. The bundling places are equipped with trough-like receptacles,formed by curved arms 22 (Fig. 2) which are rockingly mounted at 23 onthe frame of the shaking device and are held in their raised position bymeans of fingers 24 rotatable about an axis 25 and counterbalanced at26. The fingers 24 are controlled by means of pedals 21 provided at thebottom of the bundling places A, the connection between the pedals 21and the fingers 24 being effected by any suitable means not shown.

Below the curved arms Hand in front of the bundling places A is provideda second roller table 28 which extends beyond the shaking dethe scope ofmy invention. Thus it is possible being separated.

and hole-connection of their respective angular V supporting extensions32 and 33 with their brackets.

In operation, the rods are fed .to' the coldshear H] in groups up to150, are cut into commerciallengths and then are delivered to therollertable l2.

moved step by step along the roller table, until the whole length of thelatter is taken up by the groups. The various groups of rods are thentransferred by means of the rocking members; 3 a

to the inclined surface 2!] at the bottom end of which they. arearrested by the stops 2| thus being piled up in heaps. Afterthe-withdrawal of the stops 2!, the rods pass on to the bars I31 and l3'of the shaking device. 7 l

The rods arriving at the. shaking device are piled up without anydefinite order in a tangled state and matted more or less together. Bythe continuous alternate up- -and down-movement, however, of the bars'l3and I3, the rods are separated from each other spreading out in a.

single layer in spaced apart relationship so that they-can be easilygrasped one by one by hooks. The upanddown-movement of thebars l3 andI3; at the same time causes the rods to be gradu-..
